There may be other Chromium-based browsers which do this, but none that I use: on launch the user is (optionally) prompted with a profile selection tool, with additional options to create a new profile or go into a guest session. I appreciate this because without it I often end up wondering why something isn't behaving properly, and after a moment of confusion then realize I'm in the wrong profile.

It's not perfect, and I prefer Firefox's rules-driven containers, but for anything which requires Chrome I've found it sufficient.
